JAMES TUCKER, on WASHINGTON, DISTRICT oF COLUMBIAi STOPPER `IEOR CHAINCABLES.

Speccaton ofLetters Patent No. 26,722, dated Janury 3, 1860..,

To all whom 'it may concern:

Be it known that I, JAMES TUCKER, of the city and county of Washingtonand District of Columbia, have invented a new and useful ChainStopperfor Chain Cables; and

4I do hereby declare that the same is described and represented in `the"following specification and drawings.

To enable others skilled in the art to make and use my invention I willproceed to `de scribe its construction and operation, referring to thedrawings, in which the same letters indicate like parts in `each of thefigures.

Figure l, is an elevation of one side of my improved chain cablestopper. Fig. 2, is a plan or top view. Fig. 3, is a side elevation withone of the cheeks or stands removed so as to show the position of thechain in the stopper. y

The nature of my improvement in chain cable Stoppers consists in agroovedstock or base with a scored pawl and guiding staple or ring toguide the chain into the groove in the stock. i

In the accompanying drawings of my irnproved chain cable Stopper A,represents a port-ion of the deck of a vessel to which the bed or stockB, is firmly fastened by bolts or otherwise. This bed B, of the stopperis made of cast iron with a groove C, lengthwise through its upper sideand deep enough in the center for that portion of the link to lie inwhich stands edgewiseand projects below the `underside of the link thatlies flatwise on the surface of the b ed as shown by dotted lines inFig. 3, of the drawings; so-that as the lower edgesof the links of thechain which stand edgewise are drawn through the groove the underside ofthe links that lie flatwise are` drawn on the bed as shown in Fig. 3.

When the bed is cast of iron the cheek D, is cast with it in t-he formshown in the drawing, and the dovetailing score E, is cast `in theopposite side of the bed B, from the Cheek D, for the shank of the cheekD,

which is made `dovetailing to fitlthe in the bed and fastenedinfthescore by the; screw bolts F, F. These cheeks D, D', are

perforated `for the journals or pivots of the pawl or locking blockG,wlich ismadeof. i ,y wrought iron in y the` form gshown infthe* ldrawing and provided with an arm lII,by`` 55 as shown at I, I, for thepurpose ofapplying y which it is worked, whicharml is perforated,

ropes or chains toit, to markit, to stop and 1` i release the chaincable running `through the;

stopper. The cheeks D, D,`are` also perfo rated, for the ends of the barJ, fwhiclr pre-1 vents the arm H, from `falling over onto;

pawl G, is raised to` the chain, when the release the chain.

` There is a score K, across the end of1 the@ pawl G, which scoreis madeso wide andl deep asto allow` the end ofthe pawl topass y down each sideor astride of the linkthat stands edgewise, and betweenf` thelinkst-hat.. t lie flatwise as shown in Fig 3, solthat the" ends of thepawl comeyinlcontact-or against` the top of thebed between "thellinks ofthe" chain which lie flatwise, and stop `andhold it fast until the pawlisl raised again to 1e lease it. The cheelQD, isomitted in Fig; 3, toshow the pawl on the chain. i

. The staple L, is fastened into the `bed 13,121

to guide the chain properly intolthe stopperyg#` and I contemplate thattwo` pins, ,either with, or without rollers `on them may be:

used for the same purpose.

y so I believe I have describedand representedi` i the improved chain ycablewstoppergwhich I have invented, so as toenable any person .i

skilled inthe art tomakeanduseyit. I will now state what, I; desire tosecure by` Letters Patentto wit.

I claim the guiding staple orring inconv binationwith the groovedstockand scored pawl, arranged `to operate substantiallyas` described. y iJAMES TUCKERQ Witnesses: y y
